About this Add-on
Please uninstall any other, older variants of the add-on (the old one from "Malte Rücker" or the variant from "Intika", which can also be found here on addons.thunderbird.net. Unfortunately, it was not possible for formal reasons to combine the old variants with this newly revised add-on in one project, which is why the update from the other variants to this new add-on does not work directly either.
Quote Colors allows you to assign text and background colors to different quote levels which are applied when reading or printing mail or news messages. Five quote levels can be configured with distinct colors.
You can choose between two quoting display modes: graphical quoting with colored bars around quoted paragraphs (default), and traditional plain text quoting where each quoted line starts with one or more ">" characters. In graphical quoting, the color, position and style of the bars is adjustable.
Additionally, this add-on enables you to set up some basic message display options such as text, background, link and signature colors.
The source code of the add-on is open source and is available at GitLab.
